Fans of Dexter, a television drama that revolves around a blood spatter analyst for the Miami Metro Police Department, may think that Dexter’s job is the stuff of TV fiction; however, blood spatter is a very real field of forensic science. Blood spatter analysts are very specialized, but the need exists for more people in this field. Many bloodstain pattern analysts work in local and state crime laboratories that are associated with law enforcement agencies. Many agencies require analysts to perform additional forensic science duties.

Blood spatter analysts provide an extremely important service in specific areas of law enforcement, particularly those departments that deal with homicide and violent crime. Although the term ‘blood spatter’ may evoke some provocative images, blood spatter analysis is a specialty rooted in details, sometimes involving very little blood at all.

Career Description, Duties, and Common Tasks

Bloodstain pattern analysts examine blood that is left behind at crime scenes in whatever quantity. It can be a trace amount in the form of a trail or a print, or it can involve a large volume of blood – or any amount in between. An analyst uses several different techniques to collect evidence from the scene for later processing and analysis at a lab.

Common techniques involve taking photographs, using swabs and ultraviolet light to detect and collect trace evidence, and recreating spatter in the lab. This also requires the creation of detailed reports using computer simulations and analysis, as well as reporting findings to colleagues, law enforcement professionals, and court officials. Bloodstain pattern analysts can confirm or refute assumptions made about the crime or statements made by suspects and witnesses based on their analysis.

Steps for Becoming a Blood Spatter Analyst

Bloodstain analysis requires a meticulous and thorough understanding of the properties of blood and the human body. Anatomy plays a large role as it pertains to arterial flow and the behavior of blood before and after it leaves the body. Math and environmental science are also essential components of a blood spatter analyst’s job.

According to the Bureau of Labor Statistics, the typical education required for entry-level careers in forensic science is a bachelor’s degree in a natural science like chemistry, biology, or forensic science.1 Candidates who do not have a bachelor’s degree may be able to qualify for open positions with an associate’s degree plus job-related experience. All blood splatter analysts should expect to receive additional on-the-job training before beginning to work cases independently.

Specific classes in a bachelor’s or associate’s degree program to prepare for this career should include biology, anatomy, criminology, and statistical analysis. In a specialized program, these courses may lead into specific classes dealing with blood and pattern behavior that will help future bloodstain pattern analysts reveal such details as the type of weapon used in a crime, the location and the movement of the victim and the suspect, and ultimately the reconstruction of a crime. Once hired, blood spatter analysts attend classes and workshops to continually update their skills and knowledge.

To become a blood spatter analyst, you can expect to follow steps similar to the following:

  1. Acquire the education and experience needed for the blood spatter analyst position you are targeting.
  2. Apply for a position as a blood spatter analyst.
  3. Pass a background check.

Associations like the International Association of Bloodstain Pattern Analysts also provide training seminars to help entry-level analysts hone their skills.

Other Helpful Skills and Experience

Aspiring blood spatter analysts will find that note-taking, photography, and sketching skills will all be beneficial to the training process.
